Lenses / Re: 85mm
« on: November 12, 2013, 07:52:56 PM »
Steliosk:  Your photos do a great job of pointing out the purple fringe in front of the subject.  My testing also found green fringing behind the subject.

I found that both went away when I stopped down to about F/2.2 and the bokeh was still enough for my needs.  I never notice it in general use.  Check out my website if you like. Many of the photos were created with the 85 1.8, I love that lens and use it more than any other.

I'm afraid that if you shoot wide open, all the available 85mm lenses are going to have some color fringing somewhere.  Even if one of them is slightly superior according to technical reviews, the copy-to-copy variation and autofocus problems can still be frustrating.

Wish I had a better answer for you!

EOS Bodies / Re: Canon EOS 7D Mark II in 2014 [CR2]

I'm still loving my 5D3 and just keep my 7D around for backup.  The difference in sensor noise is so apparent in post processing, that I really don't care to use the 7D unless I'm forced to.  It's a nice handling camera, so I feel kinda bad about that.

When the 7D2 comes out, I will withhold judgement until there are many reviews addressing image quality/noise/higher ISO performance.  There will have to be a big improvement to attract my $$.

Nice shot, but a bit disturbing to the viewer having it upside down.  Why don't you flip it and repost?

Third Party Lenses (Sigma, Tamron, etc.) / Re: Sigma 50mm f/1.4 EX DG HSM

Here is another shot at F/2.  I seem to like that aperture with this lens.

The whole lens/body autofocus topic has driven photographers crazy for years.  The only thing that saved my sanity was the purchase of a 5D3 last year.  All my old lenses that drove me crazy on my 5D classic, now work perfectly. Some need a little MFA, but not much.  Even my Sigma 50/1.4 works like a champ.

I can see why Canon doesn't put MFA on the Rebel bodies - most users mount zoom lenses with fairly small apertures, so focus errors are masked by the DOF.   Although i do recall adjusting the focus on my 450D with a teeny tiny Allen wrench one time in order to make it work with my old 50/1.8   :P

Fixes a phenomenon in which the AF microadjustment value may change.*

Anybody know what that is referring to?

It looks like I can now upload an avatar if I wish.  Does anyone know the maximum size (in pixels) that can be displayed?

Landscape / Columbia River Gorge
« on: October 25, 2013, 12:53:59 AM »
I think the Columbia River Gorge deserves a thread of its own.  Here's a shot I took today featuring my trusty steed at Chamberlain Lake Safety Rest Area on the Washington side of the Gorge.  (On State Hwy 14)

If you happen to need a restroom break while touring The Gorge, I highly recommend this spot.

Technical Support / Re: dark vignette in top right hand corner- help!
« on: October 23, 2013, 10:04:07 AM »
Using my cheap radio flash trigger with Alien Bees, my 5D3 won't synch  at 1/200.  If I keep it at 1/160th, it works 99% of the time.  When it doesn't work, I get an artifact a lot like those in the photos above.

Since the action is stopped by the strobes (at least in my otherwise dim studio) I don't worry about the exact shutter speed.

EOS Bodies - For Stills / Re: when are the best Sales on 5d Mark iii?

One funny thing about the OverstockDigital.com pricing is the kits offered with various lenses.  At least the three are EF-S lenses for crop bodies.  LOL

And don't be surprised if that price changes mysteriously, it took a large jump yesterday when I happened to refresh the page.

Lenses / Re: Good or lucky copy of the 50L?
« on: October 18, 2013, 09:53:29 PM »
My Sigma 50mm 1.4 has a bit of focus shift.  That makes it a bit tricky to do micro adjustments.  Do I set it for accurate focus wide open or one stop down where I usually use it?  Hmmm.....

The only shift I could find was between 1.4 and 2.0, after that the depth of field overwhelmed it.   Pretty much what Neuro said.

This is a place where I always reach for my 135.  I added some vignetting, as I usually do.

EOS Bodies - For Stills / Re: "Downgrading" for a very specific reason
« on: October 15, 2013, 12:24:47 PM »
I don't miss my 5D classic a bit.  The LCD screen was tiny, the autofocus system sucked and it was very slow writing to the memory card.   I did like the smoothness and color of the images, but I can get the same look from the Mark 3 with Lightroom when I want it.

It's really hard for me to make a valid image quality comparison with my 5D3, or with any two cameras, because so much is dependent on the software I use for post processing.

I've only been using Lightroom for two years.  It's fun to go back and re-process the old images from the 5D classic and see what improvements I can make.
